2 Claims.

My invention relates broadly to razors and more particularly to a midgettype safety razor.

One of the objects of my invention is to provide a construction ofsafety razor of midget size which is particularly shaped to. facilitatethe use of the razor in removing hair under the armpits.

Another object of my invention is to provide a construction of safetyrazor having a quadrilateral cutting blade with opposite edges of unevenlengths shaped to enable the razor to be used in confined cuttingposition. 7

Still another object ofmy invention is to provide a construction ofrazor having a cutting blade which has the outline of a quadrilateralfigure and which may be used in confined or relatively crampedpositions.

A further object of my invention is to provide a construction of guardfor a safety razor by which a blade of quadrilateral outline may besecured in a predetermined position and prevented from slipping.

A still further object of my invention is to provide a construction ofquadrilaterally shaped securing plate for a correspondinglyshapedcutting blade having means for preventing endwise' slippage of thecutting blade.

Another object of my invention is to provide a construction of safetyrazor in which the securing means for the blade is telescopically mounted in the razor handle and connected with a plate member which extendsflush with a pair of abutments at each end of the guard in which therazor blade is mounted.

A still further object of my invention is to provide a construction ofsafety razor in which the handle is disposed at a convenient angle tothe cutting blade to facilitate a cross out instead of a straightdrawing cut against the hair for thereby increasing convenience andcomfort in shaving,

Other and further objects of my invention reside in the construction ofa safety razor as set forth in the specification hereinafter followingby reference to the accompanying drawing in which:

Figure 1 is a top plan view of the safety razor constructed inaccordance with my invention; Fig. 2 is a front elevation thereof; Fig.3 is a central vertical longitudinal section on an enlarged scale takenon line is a transverse vertical section on line 4- -4 of Fig. 1; Fig. 5is a perspective view ponent parts constituting the safety razor; Fig. 6is a plan view showing a modified form of construction; and Fig. l is afront elevation thereof.

to the drawing in detail, reference character 1 designates the handle ofthe safety razor of my invention having an axial bore 2 extendingtherethrough for a distance slightly morethan one-half. of the lengththereof. larged bores 3 and 4 of different diameters are formed in thehandle 1 over the remaining lengthof the handle 1. A shoulder 3ainterconnects the bore 3 with the bore 2. A shoulder 4a interconnectsthe bore 4with the bore 3. That is to say, the handle 1 has .an axialbore extending therethrough which increases in diameter in progressivesteps. The external surface of the handle 1 is provided with knurledportions 5 disposed at spaced intervals along the length of the 1. Theend of the handle 1 extends at an acute angle a to the plane surface ofthe supporting plate 6. The supporting plate 6 has an aperture '1therein through which the end of the handle 1 Referring extends forforming a soldered connection with the plate 6, the end of thehandlel-terminating fiush with the upper plane surface of the support--u ing plate 6. The supporting plate 6 has a plane surface having theoutline of a quadrilateral fig ure. Theendsof the supporting plate 6 areturned upwardly at 8 and9 forming walls extending normal to the planesurface of the support- I ing plate 6., 8 and 9 are unequal in lengthand are tapered from a maximum height atthe rear edge 10 of thesupporting plate 6 to the front edge 11 thereof which terminates in aguard as shown. The rear edge 10 and the guard 11 are The supportingplate 6 is so shaped that the angles between the vertically extendingwalls .8 and 9 and the rear edge 10 are obtuse while theangles betweenthe vertically disposed walls 8 and 9 and a peripheral line whichincludes the extremities of the guard 11, are ac te. A razor blade 20which corresponds in outline to the supporting plate is adapted to bemounted on the supporting plate 6 and secured in position between thevertically disposed walls 8 and 9 with the cutting edge 22 thereofdirectly aligned with the guard 11. The razor blade 20 is apertured at23 with the aperture directly aligning with the bore 2 in the handle 1':The razor blade 20 has edges 22, 26, 28 and 29 of unequal length, theangles between the edge 26 and edges 28 and 29 being obtuse, and theangles between the cutting edge 22 and the edges 28 and 29 being acute.

The securing plate 12 by which the razor blade 20 is maintained in fixedposition is tapered in thickness from a rear edge 16 to a front edge 21with the edges 18 and 19 thereof inclined to fit The enhandle 15 bimmediately between the vertically extending walls 8 and 9 of thesupporting plate 6. The securing plate 12 is apertured at 14 forreceiving the rod member 15 which extends through the bore in thehandle 1. That is, rod member 15 passes through the progressivelyincreasing bore in handle 1 throughout the portions 2, 3 and 4. The endof the rod 15 is screw threaded at 30 and is engaged by the screwthreaded bushing member 24. The screw threaded bushing member 24 has 2cyn of reduced diameter indicated into the end of the enlarged bore 4 inhandle 1. threaded at 27 to engage the screw threads 30 on the end ofrod 15, for securing the rod 15 in position on the handle of the razor.The fact that the handle 1 is disposed at an angle to the supportingplate 6 enables the cutting operation to be effectively in a crosswisedirection instead of a direct drawing of the razor blade downwardly in astraight line against the hair. Where it may be desirable to use therazor in straight line operations against a beard the handle 1 may bedisposed normal to the supporting plate 6 as shown in the modified formof the razor of my invention illustrated in Figs. 6 and 7.

As shown in Fig. 1, the guard 11. is provided with teeth 11a formed byslots 11b disposed at an angle of substantially 45 to the front line ofthe guard 11. Hence the teeth impart to the hair a diagonal approach tothe edge of the blade, causing a shearing action and thus greatlyfacilitating the cutting of the hair and positively avoiding any pullingor drawing on each individual strand of the beard. Furthermore, lookingat Fig. 4, it will be noted that the extreme bottom edges of theinclined slots 11b between the guard teeth 11a are beveled rearwardly asindicated at 11c, greatly facilitating the drawing of the body of thesafety razor across the surfaceto be shaved. There is a distinctcoaction between the beveled' top surface 11d and beveled lower face lieof guard teeth 11a. The beveled rear edges of the guard teeth 11a areplainly shown in Fig. 4 in full lines and in dotted lines in Figs. 1 and6. This is a most important feature of the safety parts to a time-takinglathering more or less messy Bushing 24 is internally screw The razor
